The car recognizes the unique encryption code that is generated by a specific key fob. This means that even in the event that the key fob gets stolen, it can't be used to start the car.
A new vulnerability allows thieves to take advantage of this type of communication. Relay attacks are carried out with devices that transmit at the same frequency as a key fob. Thieves can put one of these devices in a pocket or hiding spot to jam the lock command from a distance, according How Stuff Works Electronics.

Open Road Auto Group explains that smart key systems don't transmit the same frequency signal repeatedly in order to make them more susceptible to relay attacks. In this way a stolen vehicle can't be hotwired if it is equipped with a smart key as the encrypted signal that the key fob transmits is unique to each vehicle. This makes it very difficult for thieves to steal the car.

Security

One CR auto editor was able to walk into her Honda Accord to find the windows all down and the sunroof wide open. This was one of the reasons she was grateful for her Smart Key, which locked the vehicle automatically.
According to How Stuff Works, some smart keys make use of computer-encrypted signals to stop car thieves. This technology prevents hotwiring in which thieves steal the engine controller module (ECM) which is usually located at the front of the engine. The ECM is responsible for a variety vital functions, such as transmission control and engine power.
Smart keys also come with anti-theft codes, as well as an unique security code for ID assigned to each key. This will disable the ignition if the wrong key is used. The security ID is a code that is transmitted from the ECM to the key after it's placed into the ignition. It is then confirmed by a sensor in the car.
